When I try to load the code I get a fault, "Load failure: Ef(11). No Flash configured".
The sample project flashes fine. The project I created, when I try to load that, I get this fault.
The project that flashes have the Default Flash driver setting as this,

My project's(Which doesn't flash) GUI Flash Tool looks like this,

Also in my project folder I have two folders missing, ".mcuxpressoide_packages_support" and ".metadata". Not sure if it has anything to do with the flash fault.
